Thank you for the query.
It is not a good idea to take kids to the hospital. Children have weaker immune system than adults. So he might caught something and it does not have to be C.Difficile. Other bacterial infection or viral infection can be also the reason.
I suggest you to wait a day and see how the symptoms will be developing. In case of high fever
, blood in stool
you should consult a doctor as soon as possible. If the symptoms wont go away in a day, doctors attention is also required.
Please give him plenty of liquids.
Hope this will help.
